Answer:

2x - 5 = (1/2)

4x - 10           [multiply by 2]

 x - 10 = -13                 [subtract 3x from both sides]

  x = -3                        [add 10 to both sides]

Step-by-step explanation:

The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."

"Twice the value of a number" is simply 2x.

"Five less" is simply -5, so for the first part we have (2x-5)

Examine the second section next. "Three times four times more than one half the number."

"Three times the quantity" simply indicates "three times something."

4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."

So the second part is simply 3(4+x/2).

Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.

2x-5 = 12 + (3/2)x

2x-(3/2)x = 17

x/2 = 17

x = 34

Therefore, the required number would be 34.

Answer:

The answer would be B- 6s+48=258

Step-by-step explanation:

This is because she earns 6 points each time she goes so it would be 6*s, and she already has 48 points so thats where the +48 comes from

:)

The expression for the situation is binomcdf(500, 0.5, 450).

The correct option is B.

The probability distribution of random variables is described using the cumulative distribution function. The probability for a discrete, continuous, or mixed variable may be described using it. The cumulative probability for a random variable is calculated by adding the probability density function.

Given:

A coin is flipped 500 times.

The probability when the coin is flipped once,

= 1/2

= 0.5

we want P (X ≤ 450), and this will use a binomial cumulative distributive function,

the parameters of a binomial cumulative distributive function are,

binomcdf (total trials, probability, up to some number)

That means,

binomcdf(500, 0.5, 450)

Therefore, binomcdf(500, 0.5, 450) is the required expression.

Answer:

y = 14

x = 10

Step-by-step explanation:

Here, we want to get the value of x and y

Since all sides are equal, then the measure of each angle is 60 degrees

Since AC = 14

y is also 14

Also;

Since each angle is 60

Then;

6x = 60

x = 60/6

x = 10

Answer:

answer is B

Step-by-step explanation:

Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.

Step-by-step explanation:

The value of y is -8

"The slope of tee line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"

"The point at which the graph intersects the Y-axis."

"y = mx + c, where m is the slope of the line and c is the Y-intercept."

For given question,

We have been given the graph of a line.

From the graph, we can observe that the line is passing through the points (4, 4) and (-6, 0)

Using slope formula the slope of the line would be,

[tex]\Rightarrow m=\frac{4-(-6)}{4-0}\\\\\Rightarrow m=\frac{10}{4}\\\\\Rightarrow m=\frac{5}{2}[/tex]

Also, the line intersects y-axis at y = 2

This means the y-intercept is c = 2

Using the slope-intercept form of the line the equation of the line would be,

[tex]y=mx+c\\\\y=\frac{5}{2}x+2[/tex]

Point E(-4, y) lies on the given line.

So, this point satisfies the equation of the line.

[tex]\Rightarrow y=\frac{5}{2}(-4)+2\\\\ \Rightarrow y=-10+2\\\\\Rightarrow y=-8[/tex]

Therefore, the value of y is -8

Step-by-step explanation:

Answer:

BC is 10 unit

BD is 15 units

Step-by-step explanation:

Here, given the end points of the line segments, we want to calculate BD and DC

Mathematically, the distance between two points can be calculated using the formula;

D = √(x2-x1)^2 + (y2-y1)^2

For BD, we have the following

D = √(14-5)^2 + (14-2)^2

D = √(9)^2 + 12^2

D = √81 + 144

D = √(225)

Distance BD is 15 units

For BC, we have the following

D = √(11-5)^2 + (10-2)^2

D = √(6)^2 + 8^2

D = √100

D = 10

Step-by-step explanation:

length times width = area

so you have 8.5w=93.5

divide 8.5 on both sides to get your answer

w= 11

so your width must be 11 inches

Answer:

The answer is 9!

Step-by-step explanation:

Ik this is late but for people in the future, the answer is definetly 9.

180 = 6x + 6x + 8x

Now substituting 9 in for the x values;

180 = 6(9) + 6(9) + 8(9)

180 = 54 + 54 + 72

180 = 180
